If the crank actually fits BBright it'll put the pedals in the right place. The NDS is no wider than external bearing cups on a BSA BB or BB92/86.Many cranks have spindles long enough for BBright. It's just the short spindle BB30 ones that don't fit.

I just don't get the continued fascination with mating a Hollowgram to a BSA BB

Yeah, that it a valid point but that argument is not quite as valid when you are talking about mating a 'hollowgram SRM' on a time trial bike with a BSA 24 bottom bracket shell and have even considered having the alloy insert in the carbon bottom bracket shell machined to accept PF30 bottom bracket.

Clavicula M3 SRM is cheaper and would be really close in weight possibly even lighter after modifications to the Hollowgram. It fits on everything too. Has anyone actually machined out a BSA frame to take a PF30? That would be an interesting read. I suppose I get it if you already own the crank.

To answer the SiSL2/bbright question: according to my measurements, using the 109mm spindle but accepting the too-narrow chainline that the 104mm spindle gave, you are still about 2mm short. The left arm will contact the lip of the pf30 cup. I wanted to try it on an r5ca (which is bbright but with direct bearings, so no extra lip), but my friend that owns one wouldn't let me mess with it...

Q. What is the difference between BBright™ and BB30™?A. For the crank, BBright™ uses the same diameter axle as BB30™, with the addition of 11mm length on the left side of the spindle, and the left crank is straighter, (similar to existing arms for external bearing cranks).

Just putting a BB30 crank on a longer spindle will put the NDS pedal 11mm to the left, and increase the Q factor as well as making it asymmetric.

It requires a different, actually more conventional, shaped NDS crank.
